Multiple Linear Power Controller with
ACPI Control Interface
The ISL6506 complements other power building blocks
(voltage regulators) in ACPI-compliant designs for
microprocessor and computer applications. The IC
integrates the control of the 5V_DUAL and 3.3V_DUAL rails into
an 8 Ld EPAD SOIC package. The ISL6506 operating mode
(active outputs or sleep outputs) is selectable through two
digital control pins; S3 and S5.
A completely integrated linear regulator generates the
3.3V_DUAL voltage plane from the ATX supply’s 5V_SB output
during sleep states (S3, S4/S5). In active states (during S0
and S1/S2), the ISL6506 uses an external N-Channel pass
MOSFET to connect the outputs directly to the 3.3V input
supplied by an ATX power supply, for minimal losses.
The ISL6506 powers up the 5V_DUAL plane by switching in
the ATX 5V output through an NMOS transistor in active
states, or by switching in the ATX 5V_SB through a PMOS (or
PNP) transistor in S3 sleep state. In S4/S5 sleep states, the
ISL6506 and ISL6506B 5V_DUAL output is shut down. In the
ISL6506A, the 5V_DUAL output stays on during S4/S5 sleep
states.
Functionally, the ISL6506 and ISL6506B are identical. The
ISL6506B, however, features a 2A current limit on the
internal 3.3V LDO while the ISL6506 has a 1A current limit.
The ISL6506A has a 1A current limit on the internal 3.3V
LDO.
